Abstract (en)
[origin: EP0098603A2] A sheet material consisting essentially of bundles of ultrafine fibers comprises an entangled core portion and at least one super-entangled surface portion. The super-entangled arrangement has been obtained by treating at least one surface of said core portion with high speed fluid jet streams in order to obtain an entanglement density corresponding to an average distance between adjacent entangling points not greater than about 200 microns. <??>The ultrafine fibers forming said bundles of ultrafine fibers include at least two types of ultrafine fibers, the materials thereof differing in dyeing capability and showing different colours after being dyed. Said sheet material has been dyed with one or more selected dyestuff(s) in order to provide a melange-coloured surface appearance. Due to the combination of superentangled surface portion and melange-coloured surface appearance, said sheet material is excellently suited for the application as grain-type artificial leather and for other apparel use.
